Question

Expand ‘ELISA’ְ. Why is this method preferred over conventional methods of diagnosis of diseases ?

Answer 1

Answer:

Explanation:

ELISA: Enzyme-linked immunosorbent assay, a rapid immunochemical test that involves an enzyme used for measuring a wide variety of tests of body fluids. ELISA tests detect substances that have antigenic properties, primarily proteins rather than small molecules and ions, such as glucose and potassium.

ELISA is based on the principle of antigen-antibody interaction. This method is preferred over conventional methods of diagnosis of diseases because these tests are more accurate and are highly sensitive, specific as compared to other methods used for detection of antigens or antibodies.
